Add another 20 Rubicon to the list. Did it stock and still does it lifted on 37’s. Adjustable arms and have moved pinion from +1 to -3 and no change. I’m going to put Fox ATS steering stabilizer on to see if it will dampen the vibration in the steering wheel.
It’s the tailgate mechanism that stops the door from swinging out. It binds up. There are 2 bolts where the mechanism goes into the tub. Loosen the 2 bolts and let the catch move as far forward as it will go. It will move enough to free the strap from binding.
